JOHN RIDDELL, or

To all whom it mag/concern:

Be it known that I, JOHN RIDDELL, a citizen of the United States,residing at Schenectady, county of Schenectady, and State of New York,have invented certain new and useful Improvements in Slotting andShaping Machines, of which the following is a specification.

My invention relates to a portable, universal slotting and shapingmachine of the pneumatically-actuated type.

I have designed the machine for shaping and slotting cast metal nozzlesfor elastic longitudinall fluid turbines, and shall describe the same inthis connection; such work bein illustrative of what the machine iscapab e of doing. But I desire to be understood as not limiting theinvention to this use.

For a detail understanding of the inven tion reference is to be had tothe following companying drawings, and the novel features of theinvention will be pointed out in the claims appended thereto.

In the accompanying drawin which illustrate one embodiment of. theinvention, Figures 1 and 2 are perspective views of the machine mountedon the work, the views being taken from opposite sides thereof; Fig. 3IS a front view of the machine drawn on a somewhat larger scale; Fig. 4is a longitudinal section of the machine; Fig. 5 is a transverse sectionon line 55-of Fig. 4; Figsifi and 7 are. longitudinal sections of thepneumatic motor for actuating the tool showing the parts in differentoperating positions;.- Fig. 8 is a cross-section taken on line 88, F ig.7; F ig.'9 is a detail sectional V ew of certain piping employed inconnection with the motor; Fig. 10 is a fragmentary section of a portionof the work taken through a nozzle, and showing the tool in o eration;Fig. 11 is a perspective view of t e macnine mounted in position on thework and .provided with mechanism for moving it from one nozzle toanother; Fig. 12 is an enlarged view'of' the feed mechanism; and Fig.l3is a longitudinal section through a nozzle, showing one ofthe-prtitions removed. I

chine may, if desired, be fixed and the work mounted to turn. The axison which the machine or the work turns may be disposed in a difl'erentposition from that shown to suit diiferent requirements.

Arranged in the shaft opening 4 of the diaphragm is a vertical pivot orshaft 5 secured at a point coinciding with the center of the opening, orwhat is the same, the center of the nozzle circle. The slotting machineis attached to the center pivot 5 by means of an arm or bracket 6 whichis capable of turning there: on. Thebracket is provided with a groove 7,Figs. 1 and 2, extending in a direction at right angles to the axis ofthe pivot, and fitted therein is a tongue 8 on the bed-plate 9 of themachine. The tongue isslidable in the groove to or from the pivot,- sothat the machine may be adjusted to work at different distances fromthe'pivot 5. The bedplate 9 of the machine 1s provided with a verticallydisposed Web portion 9*, Fig. 2, in which are openings, that registerwith cor-' responding openings in the bracket 6 for receiving bolts 10,which secure the plate and the bracket together. The pivot thusconstitutes one point of support for the slotting machine. chine restsupon rollers 11 located at opposite sides of the bed-plate. Theserollers are mounted on the bed-plate in a segmental strip or bar 12,which is secured to, the plate in any suitable manner, and in the endsof the bar are formed bearing eyes 13 in which the ]0L1II12llS of therollers are mounted. The journal of each roller is squared at the outerend 14, Fig. 2, to receive a handle 15, Fig. l, by means of which therollers may be turned to move the machine bodily about its pivot inonedirection or the other.

Mounted on the upper side of the bedplate 9 is a rotatable table 16Wl11Cl1 supports the head 17. The table is provided with a pivot 18,:Figs. 4 and 5, whose axis is parallel withthat of the cen ral pivot hepivot .18 engages .a socket 19 in the bed-plate. To'turn the table andthe head The outer end of the macarried thereby, a screw or worm 20,Figs.

The plate 23direction on the other on the intermediate plate, and 1n consequence thecutting tool provided between the table and the intergroove 39 in theplate engages with a nut surfaces of the nozzles.

plate by bolts 41"arranged at diametrically radially for workin on thesurfaces a and i 7) of the nozzles, ig. 1, and also to be moved in adirection at an angle of 90 degrees with respect thereto for adjustingthe tool to a. position that will enable it to cut the surfaces of thenozzles. To this end mounted to slide back and forth on the rotatabletable 16, at right angles to the direction of movement of the head andcarries said head with it. The. head is guided on the intermediate plateby a longitudinal dovetail tongue 24 on the bottom thereof, Figs. 1. 2,4 and 5, which engages in a correspondingly shaped guideway 25 in thetop. surface of the intermediate plate. A similar dovetail tongue 26 andguideway 27 is mediateplate, the center lines of the latter guidewavbeing at right angles to that of the guideway 25. In order to move thehead along its guideway, a screw 28, Fig. 4, is employed. This screw isarranged in a longitudinal recess 29 on the under side of the head andis mounted in a bearing 30 onv the head in which it is'free to turn.'The screw engages with a, nut 31 disposed in the recess, and rigidlysecured to the intermediate plate. The screw may be actuated in anysuitable manner. I. provide a manual means for actuatin the screw, whichincludes a, hand-whee 32, Fi 1, that is located at the front ofthe macine. The wheel is attached to ashaft 33, which issupported in brackets34 on one side of the head, and onthe rear end of the shaft is apinion35, that meshes with a gear 36. journaled on the head, which in turnmeshes with a pinion 37 carried by thescrew, Figs. 1, 2 and 4. Hence, byturning the handwheel 32, the. head can be moved in one' is fed in atadial direction with respect to the pivot 5. For laterally adjustingthe intermediate late, "and the head "therewith, a screw 38, igs. 4 and5, arranged in a 39 rigidly secured to the rotatable table, Fig. 5. end40 of the screw is squared so as to receive an operating crani, wherebythe tool maybe adjusted in a' irection to cut the The rotatable table issecured" o the bedopposite p0ints, Figs. 4 and 5, which are disposed inan inverted T-sh sipled annular groove 43 in the bed-plate. e heads ofAs shown in Figs. 1, 3 and 5, the q the bolts engagein the enlargedportion of the groove, and the upper ends thereof pass through 0 eningsin a peripheral'flange-44 on the table to receive nuts 45 by which theparts are held together.

The head 17 comprises a bracket-shaped -member having a horizontal web46 and a vertical web 47, and both are strengthened by two parallel ribs48 extending longitudinally of the head. The web 47 is adapted tosupport the tool and the motor for driving it. Arranged between the ribssubstantially in the center line of gravity of the machine,

is an inverted U-shaped link 50 which is pi voted at its ends on thebolts 49., Thislinlr is used as a means for moving the machine by ashopcrane.

The motor 51, which I have elected to illustrate in the presentembodiment. of the 'machine, is of the pneumatically-actuatedreciprocating type. Any other form of motor may be used, however, as faras the broad features of the invention are concerned. Themotor issupported in. such a manner that the tool can be moved to or from thework in a plane perpendicular to the latter, and also be moved to anyangular position relatively to the plane of the work for finishingnozzles having different angles of discharge. To this end, the motor ismounted on a vertically disposed slide 52 and is shown, asintegrallyformed therewith, Figs. 1, 2 and 4. The slide extends parallel to thevertical web 47 of the head; ortransversely to the lane of the work, andbetween the vertical s 1de-52 and the web '47 is a pivotallyshpportedcarriage'orholder 53., that carries the motor. The carriage.

is provided with a pivot 54 which engagesa socket 555 in the verticalweb of the head. and is held in position thereon by means of bolts 56,Figs. 2 and 4. The bolts extend through arc-shaped slots 57 that arestruck from the center of the'pivot 54, and screw into tapped openingsin the carriage, serving therebyto clamp the latterto the head.Thecarri'age can be turned about its pivot by an adjusting screw or worm58 mounted in brackets 59 on the upper end. of the carriage, Figf2, andmeshing with the teeth of the sector-rack 60 formed on the vertical web47 of,the head. The right end of 'the' screw is made square to receivean operating crank by which the screw is turned to ad just the carriage.The axis of the tool, when i the latter is in mid-position as shown, isdisposed m a Pl-8.Il6.Wh1Ch is more or less inclined to that of thework, and bymeans of ment is. s'ufiicientpbut the construction can 35contain the, hydraulic medium through wlnch the compressed air or otherelastic adjustments to adapt the machine. for dlfs ferent classesofwork. The tool is adjusted .to or'from the work movable on the head.

The pneumatica-lly-actuated motor comprises a piston 65, Figs. 4, 6reciprocates in a cylinder 66. The cylinder is arranged concentricallywithin a cylindrical casing or shell 67, formed integral with the slide52 and in which the cylinder fits in such a" manner as to provide anannular space or reservoir 68, that is adapted to fluid under pressureacts ing the working stroke.

serted into the casing from one end that is normally closed by aremovable head 69, bolted in place, Figs..2 and 6; The opposite end 0the casing is cast with a hollow extension 70, which constitutes theguide for the piston-rod 71, and the tool-bar 72 se- The extension isprovided with a sleeveor lining 73 for the piston rod, and betweentheinner end ofthe same. and

The tool-bar 72, which is screwed to the outer end of thepiston-rod, pro ects beyond the end of the extension 70, and carries thecutter or tool 7 6 at its 'outer end. The iston 65 is of thedouble-acting on the piston durports 77 and78 at its opposite ends, eachof which serves to admit and exhaust the me: dium that operates thepiston. The port 77 is connected with .a source of elastic fluid, suchas compressed air, through a pipe-or conduit 79.

At the junction of theconduits 79 and 80 is athree-way admission andexhaust valve '82 which is supported onthe'rasing 67 bya bracket 82*,Figs. 1., 6' and 7.. This valve admitscompressed air to the reservoir for forcing the liquid into thecylforwardstroke of the' piston, from the forward side'of the .piston.It also alternately admits compressed air to the forward side of thepiston to cause the return stroke thereof, while simultaneously 70 aconduit 81, Figs-'1 and 6,"through which exhausting the air from thereservoirto per-- mit the return. of the liquid and hence the returnstroke of the piston. The three-way valve, Figs. 6 and 7, comprisesacasing 83 having an inlet passage 84 connected with a source of air orother elastic fluid under pressure, an exhaust passage 85 connected with.the atmosphere, and passages--86 and 87 connected respectivelyto theconduits 7 9.

and 80. YVithin the casing is a sleeve 88 register with the passagesenumerated. Within the sleeve is a hollow cylindrical valve 89, that; isprovided withan enlarged inlet port oropening 96 which is adaptedtopermanently communicate with the inlet passage 84,-sep'arate admissionports 91 and 92, which communicate one at a time with their respectivepassages 86 and 87, and an enlarged exhaust port. 93, the latter beingarranged to connect one of the passages. 86

. provided with openings which permanently .and 87 with theexhaustpassage 85, while the other passage registers with its correfspondingadmission port, thus permitting air to be supplied to one conduit andexhausted from the other. The valve is adapted to be automaticallyoscillated sb that air pressure is applied alternately and in regularsuccession, directly on the front side of the piston and indirectlythrough the liquid is reciprocated. p In order to regulate the speed ofthecutting stroke of the tool, a throttle valve 94, Figs. 6 and 9 isprovided in the connection 81 between the reservoir and 1 the cylinderof the motor, by which the rate of flow from the former to the'latte'rmay be varied, andconsequently the rate of travel of the piston. -Inorder to permit a quick return stroke of the piston a by-pass 95 iscon-- -'med1um to the rear side so that'the piston nected,around thethrottle valve, whereby a 1 relatively unobstructed return of the fluidto the reservoir is permitted. A check valve 96 is arranged in theby-pass, which opens toward.jthe reservoir, but' closes towardthecylinder thus preventingh the liquid from insuringa quick retu'rn Strthe head 69 of the motor, and" telescoping in, the bore 98 inthe innerend of the pistonrod, Figs. 6 and 7. The spindle and the piston rod aresplined together by means of a feather 99, rigidly connected to thelatter and movable ina groove'lOO extending longitudinally of thespindle. By'this means the piston is capable of reciprocatingindependently of the spindle, and of bein at the same time adjusted bythe latter'a out its axis to change theposition of the tool. The spindleis adjusted by means of a handwheel 101 Figs. 1 and 3. The wheel ismounted on a shaft 102 supported inbrackets 103 on the motor casing andconnected with the spindle by gearing comprising a pinion 104 on theshaft and a gear 105 on the spindle. By moving the hand-wheel 101, thespindle. is rotated and with it the piston rod and the tool bar. Thismechanism may be employed for feeding the tool about its axis forcutting a cylindrical opening, but in cutting a nozzle, it is employedfor setting the tool to work on one wall after another.

The length of the stroke of the motor maybe varied as desired. This isaccomplished through an adjustable stop mechanism actuk ated by-thereciprocation of the tool-bar, or piston rod, and operating on thecontrolling Valve 82 of the motor. The extension-70. of the casing islongitudinally slotted, as is also the sleeve 73, Figs; 6 and 7, theslot- 100 of the extension being correspondingly undercutin its oppositewalls, so as to provide symmetrical overhanging shoulders 107,- Fig. 8.Arranged in the slot is a-stop-earrying frame 108 whose oppositelongltudinal walls are provided with laterally extending flanges 109which engage on the top andbot I tom of the overhanging portions 107 ofthe extension, whereby the frame is slidably mounted in the slot of thelatter. The frame itself is'provided with a longitudinal slot or opening110, in which are adjust'able stops 111 for limitin the longitudinalmovements .of'

' the tool-ho der. On the reciprocating elewith a ment of themotor-is,-a collar112, secured between the connected ends of the."piston rod and tool-bar, which collar is provided u wardlyextending-projection or engagi g' u'g 113 that disposed betweendepending lugs 113 onthe stops; so as to- 5 engage therewith atthe-"endsof the} strokes and cause a slight motion-to be imparted to thestop-carrying frame.v This movement of the frame is communicatedto thecontrolling valve through a suitable mechanism so that the motive fluidis" caused to act alternately on the opposite sides of the piston at theproper intervals.

Referring to Figs. 6 and 7, the adjustable stop 111 at the left,comprises a-bolt whose head engages with the under side of the frame108, and whose shank extends through the opening 110 thereof. On thethreaded end of the shank, is arranged a plate llir that. overhangs theupper surface .of .the

frame, and by means of the nut 116 the bolt' shank and slide along thetop and bottom surfaces 0f' the frame so-that the stop may be freelymoved onthe latter. On the top plate is pivoted an adjusting latch" orpawl 120, which is adapted to engage with the teeth of longitudinallyextending racks 121 mounted on the frame at opposite sides of the slot110'. The ri ht hand stopm'ay be readily adjusted while at the same timeit prevents creeping due to the hammer .blow effect; between theprojections 113 and 113. In Fig. 1 both stops 111'are shown similar tothe one at the left hand in Fig. 6.

The mechanism between the stop-carryingframe and the controlling'valveof the motor comprises -a lever-1'22 mounted on the bracket'123 securedto the motor casing, and

a pitman'124 that is connected to' the lever 122 at one end and at theother to a hand- Wheel 1255 attached-to the spindle 126 of thecontrolling valve, Fig.- 1. The lower end 'of the lever 122 is providedwith a pin 127 which loosely engages in a slotted lug 128 on.

the stop-carrying frame so as .to enable the rectilinear movement of theframe to be converted' into curvilinear movement of the lever. As shownin Figs. 3-, 6 and 7, the" upper end of the lever'connected with thepitm'an comprises a sector 129 that is pro-,

vided with a segmental 51012130 in which is a bolt- 131 that adjustablyconnects the pitman and the sector.

The circumference of the hand-wheel of I 'thecontrolling valve 821sprovided with -notches.132 at'two .points, Fig; 3. and bear;-

ingdigainst the'circumference ofthe 'wheel is a s rin gage' i n tE133-whoseend is adapted to ene' notches and *prevent overtravel;

of. the controlling valve 82. The notches "are arranged at pointscorresponding tosthe positionsof maximum opening of the valve, so thatwhen the spring engages in one notch the valve admits com ressed anthroughono inlet port and when it engages in the other notch the valveadmits air through the other inlet port. VVhenthe hand wheel is turnedto a point where the spring occupies a position mid-way of the notchesthe valve is in a position cutting off the supply of compressed air tothe motor.

Connected wi h the conduit 80, Figs. 3

and 11., is a valve-controlled filling connection 134, which isprovidedjwith a funnel 134. the said connection bein em )lo ed forsupplying the reservoir with liquid. In order to ascertain the level ofthe liquid in-the reservoir at filling. or at any other t me. gage cocks135 are provided inthe wall of the casing at different levels thatcommunicate with the interior thereof. In order to empty the reservoir adrain cock 136,'Figs. 3 and 6. 1s arranged in the connection between thereservoir and piston cylinder.

The motive fluid whi h furnishes the power for operating the motor maybe air,

steam or any other elasticfluid.- It is-supplied to the motor through -aflexihle tube 137 connected with the inlet passage 84 of the controllingvalve by a connection 138 in which is located a shut-off valve 139, Fig.1.' In starting the motor, the valve 139 is first opened, and the motorcontrolling-valve,

which is normally in mid-position, is turned in one direction or theother by hand to cause the ports 91 and 92 to register with theirrespective passages 86 and 87 to supply the fiuid to actuate the piston.After being once started the motor continues to operate until theoperator turns the control- I ling valve to mid-position,'or cuts otfthe supply of motive fluid by closing the shut i off valve 139.

As shown in Figs. 1' and 10, the tool op-. erating on the inc ined wall.a of one of the nozzles, the out being made from the dis:

charge end of the nozzle toward the. bowl e thereof. In settin the toolfor this opera tion the position 0 the slotting machine on thesupportingbracket 6 is first determined in accordance with the radial dimension ofthe work to be operated on. This adjustment between the machine and thebracket the tool so that it will reciprocate in a plane.

sition is obtained, while by adjusting the screwf5 8, Fig. 2, the toolcan be set to reciprocate ma plane inclined at the. desired ang'le tothat of the work. Assuming the tool to be in the position shown in Fig.1, and it is desired to begin operation: the attendant then starts themotor into operation by turning the hand-wheel 125 to the left so as -toadmit air to the reservoir and thereby cause the liquid thereinv toimpel the piston forward on the cutting stroke. Once started the .motorcontinues to reciprocate until stopped by the attendant closing thecontrolling valve 82. The tool makes'a cut on each forward stroke and atthe end of the return strokes it is fed radially step by step towardthewall a until the wall a 18 finished. If it lowered sufiiciently bymeans of the screw 62 and crank G t-to take off the proper thickness ofmetal, and the feedof the tool is then made in the reverse direction ortoward the wall 03, this being accomplished by turningthe hand-wheel 32in the opposite direction to that during the first-cut. After the wall aof. the nozzle. is finished the motor is stopped and the tool adjustedfor working on any'of the other three walls.

turned on its axis through 180 degrees to present itscutting edge to thesurface at the .required angle, and the screw 20 1s rota ed tomove'thetool into-working relation to the wall. The-tool is fed in the samemanner as during the shaping of the wall a. For shaping either of theside or tangential walls a p or d,3the tool is turned through degreesand by means of the hand-wheel 32 isadusted into ,workin relation to thewall to he operated on. T e motor isthen started and as the cuttinstrokes proceed the-tool is fed by means 0 the hand-wheel 64, whichraises'orlowers the tool to'make the successive cuts; .After all thewalls of one nozzle a're shaped, the abutment 140 is unclam'ped from thework and the machine moved along to the next nozzle by means of thedevice 15, Fig. l.- proper clampe, in place and the shaping operationcontinued as just described.

. Assuming the machine to be,operating in the position shown in Fig. 11,the tool is shaping the end wallh of a nozzle 0 ning. In this case thevalve 160 in the supp y connection 152 is closed so as to. prevent themotor 148 of'the ratchet-feeding device from operating. In other wordsthe'machines held stationary, and thefeed of the tool 1s controlled'bythe hand-wheel 32. To shape the other end wall i the tool is set toextend in the opposite by means of the direction to that shown byrequired depth of cut, and the motor is then means of the wheel 10l andthe machine is moved toward the abutment by means of the handwheel 144until'the tool is in proper relation to the wall. The tool is adjustedby the wheel or lever 64 to' make the started. The feed of the tool isobtained through the hand-wheel 32 aswasthe case in shaping the wall It.In order to shape the curved side walls f and g, the tool is turned aquarter turn by the wheel 101 and set to make the required depth of cutby means of the wheel 32. The valve 160 is next opened so that, when theair is supplied to the tool-operating motor it will alsobe supplied tothe motor of the feed mechanism. as described hereinbefore. Thecontrolling valve 82 is now opened by the attendant and the tool setinto operation.

direction opposite to that traveled during the first cut. The supply ofpower is again opened and the second cut is made as before. The othercurved wall of the opening is finished in the same manner. his to benoted that by reason of the tool reciprocating in an inclined direction,and feeding in a curvilinear path, the wall 7 of the opening will beslightly concave, while the wall 7 will be slightlyconvex, as shown inFig. 12. After the side walls are'finished the slots for receiving thepartitions are next made. The valve 160 is first closed and by means ofthe hand-wheel 144 the machine is moved. to. bring the tool into theproper position with respect to the point where theslot is to be cut. Inorder to permit the hand-wheel to 'be freely manipulated in eitherdirection at any' time, the pawl is released from the ratchet wheel andpermitted to hang in msAs the valve 160 is closed the feed mechanism isinoperative and the tool reciprocates in one plane so that by operatingthe handwheel 32 the tool is fed radially and cuts the slot, as shown inFig. 13. The slots are 5 mit the abutment to be secured at thenextnozzle, after which the work proceeds as before. The wall at the nozzleend of each slot, Fig. 13, as indicated at n is slightly out away, as bymeans of a file, and lugs formed at the corners of the partitions areturned thereof; but I desire to have it understood" that the apparatusshown is only inusna tive, and that the invention can be carried out byother means.
